            Bug ID: 125061
           Summary: LibreOffice extension LanguageTool causes CPU usage to
                    skyrocket
           Product: LibreOffice
           Version: 6.2.2.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Extensions
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: hamilton.tim at gmail.com

Description:
CPU usage spikes to 110-130% (across 4 cores) when a large document (~260
pages, mainly text) is opened.

Steps to Reproduce:
1. Install LanguageTool extension
2. Open large file
3. Observe sustained spike in CPU usage and fan spin up
4. Close file
5. Observe CPU drop and fan spin down

Actual Results:
When LanguageTool is installed, opening a large document will send
LibreOffice's CPU usage skyrocketing. After a few minutes (depending on the
size of the
document), the usage does eventually drop back down below 5% again.

When uninstalled, opening a large document inhibits a short spike in CPU
usage, but quickly drops off.

Expected Results:
Small spike in CPU usage while opening, overall slight increase in CPU usage,
total to remain >5%


Reproducible: Always


User Profile Reset: No
